Nutation is a rocking, swaying, or nodding motion in the axis of rotation of a largely axially symmetric object, such as a gyroscope or the Earth (see astronomical nutation). It may also refer to:
- In biology:
- Nutation (botany), bending movements executed by some plant organs
- In human anatomy, movement of the sacrum vis-a-vis the ilia
- The same as precession in spacecraft dynamics
- Nutation (engineering)
